. To all whom t concern.

Be it. known that we, ROY Confiamos and ISAAC Flinter, citizens of the United States, residing et Los Angeles, in the county of Leer-angeles and State of Californie, have invented certain new and useful Iniprovemens in Automatic Valves, of which the following is a speeiication.-

This invenion'relates .to valves, and has for its object ,the provision of simple and elieien. means whereby the fion" of fluid fuel employed to heat a liquid will beautomatically sei up or arrested as the flow of the liquid to he. heated is set up or arrested.

A seeonderyobjeci: of the invention is to provide a device for the .stated purpose which Will he composed of-ew'parts oompactly arranged and capable of being rapidly and easily assembled and disassembled.

The invention is illustrated in the accompanying drawings and will be hereinafter fully described, the novel features being suhsequently poined ont in theo appended claim.

. In the drawingm-Fignre is en elevation of a valve embodying our present'I invention; Fig. 2 is a vertical section of the some; Fig. 3 iop plan View thereof.

For Convenience ol' reference, we will de.- serihe the invention as embodied in a valve fitted to an apparatus in which oil is ernployed as a fuel. for heating Water.

ln carrying out she invention, we employ L casing comprising an upper or Water hea-d 1 and a lower or oil head 2 Whieh are suhstantially 4cylindrical in form and provided each with an offset or elbow 3. The upper portion of the Water head is lupwardly and inwardly beveled or tapered, as shown at 4, to provide a seat. for the valve 5, and above this valve seat thesaid head is con* strueted with :i cylindrical terminal 6 which is adaped lo he secured to the water S11-pn ply pipe. The olser 3 of the Water head Vconstitutes the outlet of the same and is internally threaded to facilitar-e lisait-aen menf to a supply pipe leading to ahoiler or other receptacle. The valve 5 is secured to the upper end lof a valve stem or rod f? which extenes downwardly through a partition and guide 8 which is disposed between the meeting ends of the two heads and is construoed to lill the said ends as clearly shown in Fig. 2; This partition and guide iswprovided with a central opening'or pas- Sage to accommodate the valve stern or rod Aand iininediaiely below the said port- -he 7 and a pecking 9 is preferably fitted within the said passage around the valve stern to preventlenkage of waer therehrou-gh.

The oi'set El the oil head consitues the outlet for the and is internally threaded o faoilitae atachnient to a hnrnereeding pipe. A port- 10 'is foi'x'nel l. in the lower wel?. of the here of the oil head said head is eonstrueed with the upwardlyr- 6.5 inclined wall di constituting a seat forthe. lower valve .l2 which is secured upon the,v lower extremity of the valve stem or rod 7, as clearly shown. Below the said valve seat,l the oil heed is constructed with a cylindrical terminal i3 which is; afdaptedto he secured to e pipe leading from .a source of oil Supply. A spring li is' coileda'round the stein valve bevveen the guide and-par- 75 tit-ion 8 and the upper valve 5 and .is norinally expanded so es to hold the two valves` raised and against their respective seats. The heads are Constructed externally with l diametrioall i opposite sleeves Orcylindrical-go l5 through which securing boltsl arel 'i passed to firmly hold thetwo heads' again-str the cent-ral annular lange 17 of tliegii-ile" and partition S. 'Vhen the seeuringnus upon these holiis 16 are turned home, theivvo heads will caused o' firmly clamp" the partition and. gui-:leso ihzit the severallparts' will be held together in their operst-ivepoi. sition and leakage of the .fluids will'befpre`fvented. i The operation of the device is believed to be obvious from the foregoing description;- taken in eonneetion with `theaocc'ix'npany in@ drawings. 'he water enters the upper endl of the water head and plays upon'the 'valve .fr against the tension of the spring 14`so that, when the Waer is turned on vand the pressure consequently overcomes the tension of the spring, the valve will be opened or 10(l moved dmvnwnr'dly so as to permit the Water 'to flow into the boiler or other reeepf 'raCIe. The downward movement ofwthe valve 5 will be transmitted directly' through the valve siem. or rod 7 to the oil valve 12 and the said valve will consequently be moved away from its seatso that the oil will be pormited `to flow to the burner. llVhen the flow of water is arrested :it The point 0i use the pressure upon the llwo 11i; sides of the valve 5 will be equalized :md

the spring i4 will then he free to uct so that it will close 'lie said valve and simuia neousiy reduce the. ow of oil to the burner. `Wl1en wateri'is again .drawn from the receptacle or boiler, ille force of the spring upon the .upper valve will be. overcome by the pre'ssgire of iie Water and die flow of he Water and the oil will be again set Our fdevie is exceedingly simple in iis construction and the arrangement of its parts andmay be manufactured at a sliglr cosi.. AS allor" the. parte are inclosed, the liabiliy of any of the working elements becoming injured or geting out of order is reduced to n minimaler-fand, as the valves are directly connected, the'eirnultaneous 0peratio'n of the sume will be insured under all conditions. Bot-l1 valves are tlneaded onio the 'valve siem, as shown and consequenly may be easily :removed from the same so as to permit thedisnssembling of he device or the assembling of' the same, as will be readily understood. As the two heads are held ogether against the centml partition and guide. by l'iolt-s inserted lirouglf sleeve-e disposed at ':liametrirelly oppoeie. g'ioinis o1" the heads and preferably formed integral therewith ille parte will be l'iositively held if; heir proper operaive positions, The valve seals :1re formed integral with the respective heads and' consequenlyeannot e'nift reiaive (o the heads so that the proper engagementof the valves and the vulve seais will aesned.

t will be observed that the dieks or vulves :are threaded onto ille ends oi he valve rod so feliahii the maier sepply is irregular and' lie flow lllciuates, the valves may be. :1djusted so .that the oil valve Will be held slight-ly away from its sent instead of resting lightly against lieseme and e small Stream. of' oil w'iil be permited ,to flow to lie burner' el ail times u'nles'e the few Shim ofi` Somewhere in the. inlet pipej` This adjiistment will prevent ne extinguislxment of .fire

Al-i the, wner Should cease te flow. 'f, under ilzeiii vaive bel its seat, when v, the oii valve would be olenea :in the oi would then again. flow to the burner and would flood ille burner and be lost beside-s tending to deniegeparte. adjacent. he burner besides 'Casing e waste oil. When the. Water pz'essnr (idly, 'tife valves ivil be edjns'ed so fha-1; i-iot'n lwill seat. Should the oil preesiire rise 'abnormallys it will close the oil valve against the pressure 0f the Water on the Weiler valve and. t-fiefrebg.' prevent lined ing of the burner and the consequent irreggnn larit-y in lie Heine. i
